DAVID B. TANGER, OF LOGAN OOUN TY, ASSIGNOR OF ONE-HALF TO CHARLES D. CAMPBELL AND HAROLD E. KNIGHT, OF BELLEFONTAINE, OHIO.

PLOW-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 254,406, dated February 28, 1882.

Application filed February 10, 1881. (ModeL) To all whom it may concern Be it known that I, DAVID B. TANGER, residing in the county of Logan and State of Ohio, have invented Improvements in Plow- Governors, of which the following in a specification.

The object of my invention is to prevent the swerving of a plow out of or into the land when the team climbs over or goes out of the I) furrow.

The invention consists of a clevis'attached horizontally to the plow-beam in customary manner and connected adj ustably by means of links with the two outer angles of an oscillat- 1 ing plate. This plate oscillates within the said links, and is perforated near its inner edge for the reception of the customary draft-link,

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in

which- Figure 1 represents a top view of my improved governor, showing in dotted lines the position of the governor when the plow is on the side of the furrow. Fig. 2 is a side view thereof.

A is the clevis, attached horizontally to the plow-beam by means of bolt B in customary manner. The outer or team end of the clevis 0 is pierced with Vertical holes 0 for the reception of bolts 0, and of such a number as to enable sufficient horizontal adjustment of the governor.

Bolted two on each side of the clevis A by 3 5 bolts 0 are bars or rods D, forming, with bolts 0 and I, links, within which oscillates a triangular or hemispherical plate or wheel, E, having its bearing on bolts I, passing through its outer angles and the forward or team end 0 of the links D. The plate E isfurther perforated at a point near the plow-beam for the connection of customary draft-link, G, by means of bolt F. The parts are so connected that by simply removing one or two bolts any portion of the device mayberemoved and replaced by a new one in case of wear or breakage.

The operation of the device is as follows: While plowing, particularly in rocky or hilly land, the horses are very liable to stumble or swerve out of the furrow; or it is sometimes necessary to turn the team out of the furrow to avoid some obstacle, while desirous of plowing close up to it; or if the horses are not well trainedthey are continually climbing over the furrow, and the plow may go some distance before the team is again brought to its place. With the old form of clevis the plow is jerked out of or into the land with every sidewise movement of the team, and it is to obviate this difiiculty that I have designed my governor. 6o

When with my governor the team starts or stumbles to one side of the furrow, draft-link G, following the single-tree, drags after it the rear end, H, of the plate E.

The distance of oscillation of a point on the plate E will differ with its distance from a line between the bolts I, and the amount of swerv ing of the plow-beam will be less the greater the distance from this line to the bolt F. Thus the increasing of the length of the links D and the plate E will decrease the side motion of and tend to steady the plow.

The holes 0 in the clevis may be of any number to permit of the proper adjustment of the links D, and so increase or lessen the oscillating motion of the plate E.

My invention is especially useful in its application to sulky-plows, rendering them easier to drive and easier on the team. It enables the team to swerve to a limited extent (two feet is sufficient) without changing the direction-of the draft.

By mounting the draft-pin or attachment in an oscillating plate, E, having the described link-connection, so that the pin will move in an are on a center back of itself, it has a tendency to settle in the mean or central position, while it is sensitive to swerving in either direction, and it will necessarily be more sensitive to deflection when near the central posi- 0 tion than when approaching either limit of its permitted motion.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Let-ters Patent: 5

1. In a plow-governor, the sliding plate E,

attached at its front end bylink-connootion to beam, and carrying a draft pin or bolt moving the engl of the plow-beam, substantially as set in an are as theteam swerves from side to 10 forth. side, as described.

2. The combination of plate E, links D, ad-

5 jnstable in olevis A, and draft-link Gr, substantially as set forth.
